Helical Stabilizer Line Routing for Chassis Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing stabilizer arrangements for motor vehicles face challenges in protecting flexible lines from damage due to relative movements and external influences, especially when routing them near the ground and around rotating wheels, which limits their flexibility and reliability.
Innovation Solution
The flexible lines are routed from a central control unit through openings in the stabilizer bearing in a helical manner around the stabilizer, with individually shielded electrical lines and a compensating electromechanical actuator, allowing for a compact and protected layout that adapts to vehicle movements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If flexible lines are routed close to the ground and near rotating wheels to achieve direct laying paths, then the path length is minimized, but the lines are exposed to damage from relative movements and external influences
Solution Approach 1:
The stabilizer bar serves as an intermediary carrier for the flexible lines. The lines are routed through the stabilizer bearing and arranged helically around the stabilizer bar, using the stabilizer bar itself as the routing path. This intermediary approach allows the lines to be positioned close to the ground (minimizing path length) while being protected by the stabilizer bar structure from external influences and damage.
2Device complexity
If multiple lines are combined in one line to simplify routing, then the routing complexity is reduced, but the flexibility of the line assembly deteriorates
Solution Approach 1:
Instead of combining multiple lines into one rigid assembly, the invention segments the lines by routing them individually through the stabilizer bearing and arranging them as separate helical strands around the stabilizer bar. This segmentation maintains the flexibility of individual lines while simplifying the overall routing through the stabilizer structure.
Solution Approach 2:
The flexible lines are arranged in a helical (curved) manner around the stabilizer bar. This curved arrangement allows the lines to accommodate relative movements and maintain flexibility, while the helical pattern itself simplifies the routing path through the stabilizer bearing opening.
3Adaptability or versatility
If flexible lines are arranged in a helical manner around the stabilizer to improve flexibility and protection, then the adaptability to movements is improved, but the installation space requirement increases
Solution Approach 1:
The flexible lines are nested around the stabilizer bar, with the helical arrangement fitting within the space defined by the stabilizer bar diameter. The lines are arranged in a compact helical pattern that utilizes the available space around the stabilizer bar, minimizing the overall volume required while maintaining flexibility and adaptability to movements.

AI summary
A stabilizer arrangement for a chassis of a motor vehicle, having at least one actuator which compensates for vehicle movements entirely or partially in the region of a wheel suspension which is connected to the stabilizer arrangement, wherein the actuator can be actuated via flexible lines. The actuator is connected to a central control unit via flexible lines to be routed from the central control unit, via openings which are arranged in a stabilizer bearing, to the actuator which interacts with a stabilizer, wherein the flexible lines are arranged around the stabilizer in a helical manner, and operation of the actuator causes a change in the diameter of the helix or the helix shape of the flexible lines which are laid in a helical manner.
